A notepad that calculates as you type.

It is available on macOS, Windows, Linux, Android and the web. The free version includes one note with unlimited calculations. An optional Lifetime purchase adds unlimited notes and cross-device sync.

## [PDF Index Generator](https://www.makeitla.st/tools/pdf-index-generator)

AI-powered book indexing from PDFs, offline and cross-platform.

PDF Index Generator is a desktop application for authors, publishers, and editors who need to create professional back-of-book indexes from finished PDF proofs. It replaces manual indexing, which can take days or weeks, with an automated process that delivers results in minutes.

The software offers two workflows. Rule-based mode builds an index from a user-provided term list. AI-assisted mode analyzes document context to suggest terms, reverse names into professional index format, and group related concepts under common headings.

Unlike online AI indexing services, the program works entirely offline, so manuscript content never leaves the user's computer. It runs on Windows, macOS, and Linux. The finished index can be appended to the original PDF or exported to DOCX for further editing.

Pricing is a one-time payment of $69.95 with no subscription or per-book fees. A free trial indexes the first 10 pages.
